摘要

本文通过理论分析、数值计算和三维仿真，设计了一种用于0.42THz te17,4模回旋管的准光模式转换器。QOMC由一个杰尼索夫发射装置和一组波束形成反射镜组成。用耦合模式理论分析了杰尼索夫发射装置的工作原理。这些反射镜用于形成波束形成反射镜系统。利用矢量衍射理论计算了反射镜上的场。对集成的QOMC进行了全面的三维电磁分析。结果表明，该方法的转化率可达98.1%以上。三维仿真结果与设计计算结果吻合较好。

Designed of a quasi-optical mode converter for 0.42THz high order mode gyrotron

A quasi-optical mode converter (QOMC) for a 0.42THz TE17,4 mode gyrotron has been designed by theoretical analysis, numerical calculation, 3D simulation in this paper. The QOMC consists of a Denisov launcher and a set of beam-forming mirrors. The operation of the Denisov launcher has been analyzed by the coupling mode theory. The mirrors are used to form the beam-forming mirrors system. The vector diffraction theory is used to calculate the fields on the mirrors. A full 3D electromagnetic analysis of the integrated QOMC has been done. Results show that a conversion efficient of more than 98.1% has been obtained. Results of 3D simulations are in good agreement with the design calculation.
